14 June 1990
An interim forensic report, signed by Hayes and Feraday and dated 14 June 1990,
stated in its last paragraph that attention had been focussed on identifying those
surviving parts of the IED including electronic or electro-mechanical timing
mechanisms and altitude/pressure sensitive switches and that
“To date none has been identified. Precisely how the explosive device was actuated must therefore presently remain undetermined in the absence of any clearly identifiable component parts of the firing circuit.”
This post ends Part II of the Chronology of PT/35(b) . I shall now write about PART III which covers the “identification” of PT/35(b) by FBI Thomas Thurman and the subsequent investigation of MEBO and the MST-13 timers.
